A tiny, rarely fertile cyonolichen, forming black cushions composed of short cylindrical lobes. The species grows on vertical surfaces of calcareous rocks, often in places where the trickling water is retained. Communities inhabiting such microhabitats are often rich also in free-living cyano-crusts. Lempholemma botryosum belongs to rather rare species in Europe and is linked to limestone areas. In the Czech Republic, it has been recently recorded only on limestones in the Český kras Karst and in the vicinity of the Rabí castle in the Horažďovice region. Historically, it was reported from the Moravský kras Karst (Černohorský et al. 1956).
